1) New bee colonies in the spring need to be fed 1:1 syrup to stimulate comb building and brood rearing since they lack honey stores. The entrance should be restricted when feeding to prevent robbing.
2) To prevent swarming, the beekeeper should checkerboard frames, keep ahead of honey production with extra supers, and perform artificial swarm splits by moving the queen and some frames to a new hive while removing queen cells from the original hive.
3) Weak colonies in late spring/summer can be strengthened by exchanging frames of sealed brood from strong colonies and providing more space with additional supers as the existing supers fill with half to two-thirds of honey.
